applicati@ sied July si,

I zen of theUnited States,residing at Pullman,

county of Cook, and State of Illinois, have invented certain new and useful Improve-v ments in Body and Truck Bolsters, of which the following 1s a specification.

Inorder to make a strong bolster with the lower plate bellied at its central portion, so as to most effectively resist the strains put upon it, I have devised a bolster which includes side plates with integral flanges at their upper and lower edges. p The upper llanges are turned outward for substantially the entire length of the plates, while the centrall lower portion of the plates has outwardly-turned flanges and the intermediate and end portions have inwardly-turned flanges. Coperating with these lower flanges is a bottom tie-plate which ta ers towar its ends, said plate being rivete to the flanges. By using such a ta ering tie-plate I not only make the bolster o a sha e to effectively withstand its strains, but I a so save metal whereit is not needed and economize in weight.

The flanges of each bolster-plate may be' turned over when the plate is either hot or cld; but I preferably perform the operation when the plate is cold. By this method the metal is not stretched or subjected to attenuation, but remains of a uniform thickness throughout. In addition to these advantages I am enabled to employ a heavy tension-'plate at the bottom, and the same can beeasil riveted tothe flanges of the side dates, ecause they are readily accessible,

eing turned outwardly, at least at the central art. p In the accompan -ng drawings I have illustrated one embo iment of my invention, wherein- Figure 1 shows a perspective view of my improved truck-bolster. Fig. 2 is a side elevation of the body-bolster. Fig. 3 is a similar view of the truck-bolster. Fig. 4 is a horizontal section of the body-bolster on the line 4 4 of Fig. 2. Fig. 5 is a partial top plan and artial sectional View of the' truckolster illustrated in Fig. 3. Fig. 6 is a vertical longitudinal section of the body-bolster. Fig. 7 is a vertical longitudinal section of the truck-bolster. Fig. 8 is an end view of both holsters, and Fi 9 is across-section of both bolsters on the line 9 9 of Fig. 4.

A -Each bolster comprisestwo side plates 1 1, eac'l of-which has an outwardly-turned flange 2',. ,extending along lthe greater portion of its upper edge. is an outwardly-turned flange 3 at the central ortion and inwardly-turned flanges 4 at the intermediate inclined and end portions of the sides.

tending flanges 2. A bottomplate 6, which is widest at its central portion 7, and which tapers, as at 8 8, toward its ends, which have parallel edges 9 9, is riveted to the flanges 3 eurely tie together the lower portions of the plates 1 1 and secure great strength because of the width ofthe central portion of the tieplate, which is riveted to the outwardlyturned flanges.

The body-bolster has its side plates 1 1 spaced apart at their ends by means of dishs aped sheet or castmetal parts 10, which are riveted to the side plates 1 1 and also secured to the flanges 4 and the bottom plate 6.

The truck-bolster constructionally follows the bodybolster but its side plates are spaced apart and strengthened at each end by means of two dish-shaped plates 11 11, these plates being riveted to the side plates flanges 4 4. This construction is clearly illustrated in Figs. 1 and 7.

rivet the center-bearing plate 12, which is provided with an annular rib 13 which acts as a bearing. The plate 12 is secured to the under side of the body-bolster by means of rivets passing through the bottom tie-plate 6 and the central outwardly-turned flanges 3 3.

On the upper side of the truck-bolster I rivet the cooperating center-bearing plate 14, having the annular rim 15, within which fits the rim 13. These two bearing-plates 12 and 14 act together to form a strong and easilyconstructed center-bearing. The plate 14 is secured to the top ofthe truck-bolster by means of rivets passing through the top plate and the outwardly-turned flanges.

As a filler king-pin block I provide the casting 16, Fig. 4, which has oppositely-ex-` tending flanges at each end' riveted to the side plates 1 1..

through its center. The truck-bolster is supand 4. By means of this tie-plate 6 I se- 1 1 and also to the lower tie-plate and to the- To the lower side of the-body-bolster I` The central portion of the 'A block has a hub 18 with a cylindrical bearing At thelower edge of each plate I A top plate 5 covers the plates 1 1 I and is riveted to their upper outwardly-exv IOO plied with a similar block and the king-pin 19 when in place passes through and has its bearings in the two hubs 18, as is illustrated in Fig. 9. l

'It will be apparent to those skilled in the art that I have devised an extremely simple and at the same time unusually strong form of bolster which may be used either as a bodybolster or a truck-bolster, or bot Various modifications may be made in the structure herein described which would fall within the spirit and scope of the invention as defined in the followin claims.

This patent is intended to embrace only so much of the disclosure made herein as is covered by the claims.

I claimy 1. In a bolster, the combination bellied side plates, and a bottom broadest at its central ortion and tapering toward its ends fastened) to said side plates', substantially as described.

of spaced 2. In a bolster, the combination of bellied'- side plates, a top plate riveted to said side plates, and a tapering bottom plate riveted to said side plates, substantially as described.

8. In a bolster, the combination of bellied side pla'tes with top and bottom flanges, a rectangular plate riveted to the top flanges of said side plates, and a tapering plate riveted to the bottom flanges of said side plates,substantially as described.

4. In a bolster, the combination of bellied side plates with top and. bottom flanges, a rectangular plate riveted to the top flanges'of said side plates, and a tie-plate broadest at its center and tapering toward its ends riveted to the bottom flanges substantially as described.

5. A bolster provided with a side plate havtie-plate of said side plates,-

ing an integral bottom flange turned laterally in one direction, and another integral bottom flange turned laterally in the opposite direction, substantially as described.

6.' A bolster provided with a side plate having a to flange extended in one direction, a bottom ange extended in the same direction, and another bottom flange extended in the opposite direction, substantially as described.

7. A-bolster provided with a side plate having an integral top flange turned in one direction, an integral bottom flange turned in the same direction, and another 1ntegral bottom flange turned .in the opposite direction, substantially as described.

8. A bolster comprising two side plates havin outwardly-turned upper flanges, and inwardly and outwardly turned lower flanges, a plate riveted to the upper flanges, and asecond plate riveted to the lower flanges, substantially as describe 9. In a bolster, the combination of two side plates having outwardly-turned upper flanges, and inwardly and outwardly turned lower flanges, of a plate riveted to the upper' flanges, and a tapering plate riveted to the lower flanges, substantially as described.

10. In a bolster, the combination of two side plates having outwardly-turned upper flanges and inwardl and outwardly turned lower flanges, of a plate riveted to the upper flanges, and a second plate broadest at its center and tapering toward its ends riveted to the lower flanges, substantially as described.
